Abstract

The invention provides a method for improving cotton verticillium wilt by utilizing an inducer. A salicylic acid solution having the concentration of 0.5-10 mmol / L is adopted as the inducer, the SA solution is consistent with an NPR1 disease-resistant expression induced by the verticillium wilt in mode, the SA solution is sprayed to cotton leaves in three days before the verticillium wilt appears so as to obtain verticillium wilt resistance, and then the SA solution is then sprayed one time every 3-5 days so as to maintain the disease-resistant level in cotton seedling bodies. The salicylic acid solution is adopted as the inducer to induce change and produce the verticillium wilt resistance, and the damage of verticillium dahlia to cotton seedlings is decreased after salicylic acid treatment. The method is simple and low in cost, the effect of improving the cotton verticillium wilt resistance is good, and the method has a certain application prospect.

Description

technical field [0001] The invention relates to a method for improving the resistance of cotton to Verticillium wilt, in particular to a method for improving the resistance of cotton to Verticillium wilt by using an inducer. Background technique [0002] Cotton is an important economic crop in my country and one of the main raw materials for national defense, textile, chemical and other industries. However, cotton pests and diseases have always restricted the development of cotton planting industry, especially verticillium wilt, known as the "cancer" of cotton, which has a significant negative impact on the yield and quality of cotton. [0003] At present, there are many methods to improve the resistance of cotton Verticillium wilt. Among them, the use of microbial agents such as Bacillus subtilis or Bacillus combined with chemical agents can improve disease resistance, but the extensive use of pesticides pollutes the environment and destroys the ecological balance of farmla...
